The Bottom Line		While the picture quality of the LG LK450 has its strengths, they're overcome by its grayish reproduction of black.	The Vizio E3D0VX series has excellent features for the price, including 3D and robust streaming, but its 2D picture quality is a big Achilles' heel.	Despite being unable to fulfill the expectations raised by its specification sheet, the Vizio E-Series remains a good choice if you value its Smarts and styling.	The LG LV5500 series is a decent performer at its price level and features a great Smart TV package, but paying a little more for a different model would reap big rewards.
